Anthurium plant named ‘ANTHDUXH’

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDUXH’ particularly characterized by having bright, shiny, cordate spathes, a light pink spadix with reddish tip, a compact plant habit and outstanding long cordate leaves, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDUXH’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHDUXH’. The new variety originated from a hybridization made in December 2006 in Bleiswijk, The Netherlands. The female parent is a red Anthurium pot plant designated ‘4110-04’ (unpatented), and the male parent was a red Anthurium plant designated ‘5442-01’ (unpatented).

A single plant was selected in November 2008 and has been asexually reproduced repeatedly by meristem tissue culture in Bleiswijk, The Netherlands over a five-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Jul. 5, 2013, in China on Jan. 29, 2015 and in Taiwan on Feb. 5, 2015. ‘ANTHDUXH’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Bright, shiny, cordate spathe;     -   2) Light pink spadix with reddish tip;     -   3) Compact plant habit; and     -   4) Outstanding long cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 25-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in February 2015.

FIG. 3 shows the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHDUXH’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 25-week old plants which were planted from tissue culture in 14-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in February 2015. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDUXH’ differs from the female parent plant ‘4110-04’ (unpatented) in that ‘ANTHDUXH’ has a dark red spathe, whereas ‘4110-04’ has a bright red spathe.

‘ANTHDUXH’ differs from male parent plant ‘5442-01’ (unpatented) in that ‘ANTHDUXH’ has a light pink spadix with reddish tip, whereas ‘5442-01’ has a white spadix with yellow tip.

‘ANTHDUXH’ differs from commercial variety ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) in that ‘ANTHDUXH’ has a light pink spadix with a reddish tip and long cordate leaf blade, whereas ‘ANTHEPEDI’ has a white spadix and cordate leaf blade. Additionally, ‘ANTHDUXH’ has a longer spadix than ‘ANTHEPEDI’.

‘ANTHDUXH’ differs from commercial variety ‘ANTHOLODOJ’ (U.S. Plant Pat.

Additionally, ‘ANTHDUXH’ has a 90 degree angle between the spadix and spathe, whereas ‘ANTHOLODOJ’ has a 40 to 60 degree angle between the spadix and spathe. 

I claim:
